[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are just examples and are not intended to limit the present invention.

[0030] The following describes a moisture-repellent AC motor according to an embodiment of the present invention with reference to the accompanying drawings. Figures 1-9 As shown, the moisture-repellent AC motor includes a housing 1, a first end cover 2, a second end cover 3, a shaft 4, a stator assembly 5, a rotor assembly 6, and a fan blade 7. The first end cover 2 is located at the front of the housing 1, and the second end cover 3 is located at the rear of the housing 1. The shaft 4 is rotatably mounted on the first end cover 2 and the second end cover 3. The stator assembly 5 is installed inside the housing 1, and the rotor assembly 6 and the fan blade 7 are mounted on the shaft 4. The rotor assembly 6 is located inside the stator assembly 5, and the fan blade 7 is located behind the rotor assembly 6. A support frame is provided below the housing 1, and a junction box is provided on one side of the housing 1. The stator assembly 5 is electrically connected to the junction box.

[0031] In a specific embodiment: during use, the junction box is connected to an external power source, thereby energizing the electronic components to generate magnetic force, which in turn drives the rotor assembly 6 and the shaft 4 to rotate, thus making the motor work.

[0032] like Figure 2 , Figure 7 and Figure 8 As shown, the dehumidifying AC motor includes a dehumidification device, which includes a guide groove 12 and a cover plate 13. The guide groove 12 is slidably installed on the lower part of the housing 1, and the cover plate 13 is fixed on the guide groove 12. The lower ends of the housing 1 are provided with guide holes 11, which are located above the cover plate 13. The lower part of the first end cover 2 and the second end cover 3 are provided with limiting plates, which are fastened to the two ends of the guide groove 12. The guide groove 12 is arc-shaped and has notches at both ends. The cover plate 13 is arched and has evenly distributed notches on both sides. Evenly distributed ribs are provided on the inner side of the cover plate 13, and the lower part of the ribs is serrated.

[0033] In a specific embodiment: When in use, the water droplets inside the motor will flow downward due to gravity, and fall through the guide hole 11 to the top of the cover plate 13. The arched cover plate 13 will guide the water droplets to both sides, and then discharge them into the guide groove 12 through the notch. Then, they will be discharged to the outside through the notches at both ends of the guide groove 12, thereby draining the water droplets inside the motor and preventing short circuits or rusting of the motor.

[0034] When external water vapor or water vapor on the guide channel 12 evaporates, it will accumulate on the inner side of the arched cover plate 13 due to the arched cover plate 13. When it condenses into water droplets or water flow, it will adhere to the ribs of the serrated cover plate 13 and drip back onto the guide channel 12, reducing the backflow of water vapor.

[0035] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the moisture-repellent AC motor includes a heating device, which includes a mounting plate 9 and a heating tube 10. The mounting plate 9 is fixed to the rear of the second end cover 3, and the heating tube 10 is fixed to the mounting plate 9. A deep hole is opened at the rear end of the rotating shaft 4. The heating tube 10 is rotatably installed in the rotating shaft 4 through a bearing. The end of the heating tube 10 is connected to a junction box through a wire. The second end cover 3 has evenly distributed through holes. The sides of the first end cover 2 and the housing 1 have heat dissipation holes. The first end cover 2 and the housing 1 are provided with dustproof plates to cover the heat dissipation holes.

[0036] In a specific embodiment: When in use, the heating tube 10 is energized and heated, thereby increasing the temperature inside the motor, evaporating the internal water vapor, and allowing the internal water vapor to be discharged through the through hole on the second end cover 3, and also through the heat dissipation holes on the first end cover 2 and the housing 1.

[0037] like Figure 7 and Figure 9 As shown, the moisture-repellent AC motor includes a ventilation device, which includes a fan 14, a diversion valve 15, and a nozzle 16. The fan 14 and the diversion valve 15 are fixed on the top of the housing 1 and are connected to a junction box by wires. The fan 14 is connected to the air inlet of the diversion valve 15. The nozzle 16 is fixed on both sides of the top of one end of the housing 1 and is connected to the air outlet of the diversion valve 15 by a conduit. The nozzle 16 is located between the stator assembly 5 and the fan blade 7.

[0038] In a specific embodiment: When in use, the fan 14 is started by an external power source, thereby blowing the external airflow into the diversion valve 15. The diversion valve 15 controls the diversion of the airflow and sprays it into the motor through the nozzle 16, thereby accelerating the airflow inside the motor and enabling the water vapor inside the motor to evaporate quickly, thereby achieving the purpose of dehumidification.

[0039] Working principle: During use, water droplets inside the motor flow downwards due to gravity, falling through the guide hole 11 onto the cover plate 13. The arched cover plate 13 guides the water droplets to both sides, allowing them to drain into the guide groove 12 through the notch, and then out to the outside through the notches at both ends of the guide groove 12, thus draining the water droplets from inside the motor and preventing short circuits or motor rust. The heating tube 10 is energized to heat the motor, raising the internal temperature and evaporating the internal moisture, which is then discharged through the through hole on the second end cover 3, and also through the heat dissipation holes on the first end cover 2 and the housing 1. The fan 14 is started by an external power source, blowing external airflow into the diversion valve 15. The diversion valve 15 controls the airflow to be diverted and sprayed into the motor through the nozzle 16, thereby accelerating the airflow inside the motor and allowing the moisture inside the motor to evaporate quickly, thus achieving the purpose of dehumidification.
